Not the OP, but my apartment building has three different types of trash containers in the yard; there's one for glass; there's one for paper, plastic and aluminum cans together (I presume because those can be separated automatically somehow), and the third is for general household waste. The garbage collection fees are based on the volume of the general waste, collecting the sorted "recyclable"(it's not necessarily recycled) trash is subsidized to be free. There's the fourth type of trash that we sort out which is things like batteries and electronics waste; these shall not be put in household waste but should be disposed in 'centralised' containers which are located at e.g. supermarkets.
